Question & Answers

Why is my Silent fan running continuously?

This may be due to incorrect wiring, please have a qualified electrician check this with the install guide and speak to the EnviroVent technical department if required. It may also be due to an incorrectly set humidity sensor (model dependant). If a humidity sensor version is fitted the sensitivity can be adjusted on the fan. Adjusting clock wise will make the sensor less sensitive, anticlockwise will make the sensor more sensitive to humidity.

My Silent fan will not run:

If a fan will not operate, a qualified electrician will need to check the wiring, ensuring the fan is wired correctly and receiving power.

Should I remove the tape on the inside of the Silent HT fan?

No, this is Hydroscopic tape, it is to protect the sensor from moisture, but will allow vapour through. Removing this may damage the sensor and invalidate the warranty.

How do I get the front cover off my Silent fan?

Always isolate power first. The cover can be removed by firstly pushing the small reseeded retaining point on one of the edges of the fan, then slowly unclipping the rest of the cover with a small flat screw driver.

What wiring does the Silent T and HT require?

The fans require a permanent live and neutral and a switch live (to trigger the fan)

Can I fit a 230V fan in zones 1 or 2 of a bathroom?

Yes, as long as the circuit is protected by a 30mA RCD

Does the Silent 100 come in Silver?

Yes, the Silent 100 is available in either white or silver.
